2 hadith
Hadith 5556
Narrated Al-Bara' bin `Azib: An uncle of mine called Abu Burda, slaughtered his sacrifice before the `Id prayer. So Allah's Apostle said to him, "Your (slaughtered) sheep was just mutton (not a sacrifice)." Abu Burda said, "O Allah's Apostle! I have got a domestic kid." The Prophet said, "Slaughter it (as a sacrifice) but it will not be permissible for anybody other than you" The Prophet added, "Whoever slaughtered his sacrifice before the (`Id) prayer, he only slaughtered for himself, and whoever slaughtered it after the prayer, he offered his sacrifice properly and followed the tradition of the Muslims."
Hadith 5557
Narrated Al-Bara': Abu Burda slaughtered (the sacrifice) before the (`Id) prayer whereupon the Prophet said to him, "Slaughter another sacrifice instead of that." Abu Burda said, "I have nothing except a Jadha'a." (Shu`ba said: Perhaps Abu Burda also said that Jadha'a was better than an old sheep in his opinion.) The Prophet said, "(Never mind), slaughter it to make up for the other one, but it will not be sufficient for anyone else after you."
